* anatomy 0.2.7 has all the work needed for the marketing site, just to
  make sure things are backwards-compatible

  * part of this removes the public/ special-casing and switches to
    template-provided css/js additions, which also will fix the
    Staticfile buildpack 1.3.3 behavior which broke the site for a bit

* broomhlda bump improves YAML and Bash highlighting
